 Yes it used to happen, I remember seeing ping responses up to 1900ms 
 instead of usual ~22ms.  However, today, what I get is just a *skip* of 
 ping sequences until I break (^C) the process requesting to much 
 traffic.  For example skipping ping probes from 510 to 523:
 64 bytes from x.x.x.x: icmp_seq=509 ttl=56 time=22.900188 ms
 64 bytes from x.x.x.x: icmp_seq=524 ttl=56 time=22.311495 ms

 When I break the pkg_add process fetching the binary from a near mirror, 
 the ping probes now resume!  So the WPA supplicant seems to be rather 
 more self-healing in -current.  Are there actually changes since 7.0_RC1 
 and current 2015-07-09?  As far as I can remember this didn't happen 
 before so I can only assume it's related to my userland upgrade.  For 
 the pings being skipped instead of getting high response time, however, 
 I don't know.
